We have no issue with the enganier they have sent out they always seem to do the best they can. Customer service is shocking. We have complained to 2 different managers and never get called back by them. The complaints don't seem to go anywhere and it's always another department's issue. The communications between the people you speak to and the enganier is shocking. We got told we need a part on the 1st job. When booking the second job we informed the person we booked the appointment with. They didn't tell the chap they sent out. Job 3 the chap had ordered the part we confirmed we needed the part, got a 0hone call to let us know he was picking up the part. Chap turned up and had no knowledge of the part and it wasn't on the paperwork! Part finally replaced (4weeks later) and the boiler serviced but still not working and have error codes and all we are getting is you will be called back shortly. Shocking from the office side no help at All!
